本文主要阐述了新炉炉衬料的基料、添加剂、配方等组成,打结与烘烤等问题、分析了此炉衬的特征、优点及经济效益。我公司中频炉主要用于冶炼低合金碳钢、高锰钢、不锈钢及合金铸铁。我们通过多次试验后发现,采用铝矾土熟料外加适量添加剂后打结的炉衬,其寿命显著提高,在同样的生产条件下,寿命提高了一倍,平均炉龄在70炉次以上,且筑炉成本也得到显著的下降。
This paper mainly elaborates the composition, knotting and baking of the lining materials of new furnace linings, additives and formulations, analyzes the characteristics, advantages and economic benefits of this lining. Our frequency furnace is mainly used for smelting low carbon steel, high manganese steel, stainless steel and alloy cast iron. After many tests, we found that the lining life of knotted lining after using bauxite clinker with proper additives has been greatly improved. Under the same production conditions, the service life is doubled. The average furnace temperature is above 70 ovens, And the furnace cost has also been significantly reduced.
